I converted a word document into a PDF file using Adobe Acrobat 6.0 Standard. Then, I merged a few PDF's together into one main PDF. After merging the files, I needed to update my table of contents. (This table of contents had already been generated in a word document before it was converted to a PDF.) My question is, is it possible to update a table of contents when it is a PDF? Thank you in advance for any help!
